The melon louse, although a dillicult insect to treat when it occurs on cucuirbits and some other plants, can be more readily (controlled on beets. In fact, all of the leaf-infesting plant-lice can be destroyed on beets by means of sprays and other washes and l)y some of the ordi- nary general methods of farm piactice. Kerosene emulsion.—The standard remedy for pla)it-lice is kcrosene- soiip emidsion, made by (•om])ining 2 gallons of kerosene, half a pound of whale-oil or lish-oil soap or 1 quart of soft soap, with 1 gallon of water. In preparing this emulsion the soap is first dissolved in boiling water and then poured while; boiling hot, but awa}^ from the tire, into th<j kerosene. The mixture is th<ni churned somewhat violently for about five minutes by means of a force pump and direct discharge.
